Glow in the Dark Filament

[Belezeebub 9]

Both the Solex and the CC Red are 300 bucks I want to print some door signs with glow in the dark on my S5 anyone got a suggestion for a filament and Hotend would be best? I am leaning towards the CC red and ColotFabb GloweFill, the CC red is ruby but the Solex is just harden steel

I use the CC red core to print abrasive materials, so also for Glowfill. Works, not problems.

 

Just one hint for the Glowfill that you are not disappointed, it will not be visible very long, maybe 20 minutes or so. So for the most use cases it is useless for me.

I have colorFabb glowfill, and indeed, it does not glow for very long. It is very bright for a *very short* time, and then quickly fades. Usefull brightness as a sign is a few minutes, maybe 5 at best. And then it is still barely visible, but unreadable, in pitch black darkness for indeed maybe 20 min. Just a blurred pale green shade. Useless as emergency exit sign, or as night-light in a room.

 

In the old days they had radio-active glow-in-the-dark paints, used on clocks. These did glow *very* bright all night, for +10 years. This was really fascinating, and very usefull. But these paints are forbidden now, even though their radio-activity level was less than the normal background radio-activity in nature. Rocks, (natural) gypsum and river-water are radio-active too. Uranium, thorium, and radio-active argon are natural elements found in the earth crust. And much of the heat in the inner earth comes from natural radio-active decay of these elements. So the whole globe is a nuclear powerplant, sort of, and even a "melt-down".  :-)
